A wave where people in a crowd throw their hands in the air (and often rubbish) in a consecutive manner moving around a stadium. Often seen at cricket and rugby games. Sometimes when the game is really exciting (or boring).

Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.

The act of nodding one's head at a friend or aquintance instead of the traditional wave.
